First Claim
1. A method of controlling an information processing device connectable to a first storage unit, a second storage unit and a data migration log area, the first storage unit including a readable and writable first memory, the second storage unit including a readable and writable second memory, the method comprising:
- executing first processing for determining a storage status of the first storage unit based on reliability information acquired from the first storage unit;
executing second processing for, when the storage status of the first storage unit is recognized as a protected state by the first processing, executing write on only the second storage unit of the first and second storage units, executing read on one of the first and second storage units based on an address recorded in the data migration log area; and

Abstract
According to an embodiment, when a storage status of a first storage unit is recognized as a protected state, a control unit writes data to a second storage unit. When a read target address is recorded in a data migration log area, the control unit reads data from the second storage unit. When the read target address is not recorded in the data migration log area, the control unit reads data from the first storage unit.
